Hi Jon, I’m sorry to hear you’re having problems and we want to get your up and running as quickly as possible.

There can be a few reasons for this. Try these trouble shooting tips and see what happens:

- It’s possible that the V72 isn’t charged at all and its completely empty, in which case the LED indicator lights will go out. Try charging the battery with a wall charger or a solar panel and see what happens then.
- It’s also possible that the device you’re trying to charge isn’t suited for 19V. The USB slot for phones/tablets only runs 5V, and camera chargers typically run at 12V, so see what the appropriate voltage is for your device and switch the V72 battery to that setting.
- Finally it’s also possible that the device you’re trying to charge is fully charged, in which case no current will flow. Sometimes customers plug everything in with fully charged phones/laptops/etc, and naturally they don’t see anything charging.
